Lowe Alpine’s AirZone Pro 35:45 is their ultimate hiking pack. Featuring an AirZone+ adjustable carry system with FormKnit technology, ventilation mesh is body-mapped to the high-sweat areas for optimal carrying comfort in warmer conditions. Top lid access and zipped side entry to the main compartment enable flexible packing, while the next-generation Spider Plate bungee system provides a secure stash option on the front of the pack. Suitable for day hikes and lightweight overnight trips, an extendable lid enables capacity to be increased from 35 to 45 litres to accommodate your camping needs.
